Abstract
The utility model provides a composite precast slab used for a laminated slab, which is characterized by comprising prestressed rib and a composite core board; the prestressed rib is a concrete product; a prestressed reinforcing steel is arranged inside the prestressed rib; the cross section of the prestressed rib is in an inverted T shape, an L shaped, a rectangle and the like; and a reinforcing steel bar connecting piece and a hoisting ring are arranged at the upper part of the prestressed rib. The composite core board is a compound body of a cross rib and a core plate and adopts bonding connection mode. The cross rib is a reinforced concrete product; the cross section of the cross rib is in a rectangle, a hemicycle and the like or the combination of the rectangle, the hemicycle and the like; and a reinforcing steel bar is arranged inside the cross rib. The core plate is made of foam concrete, aerated concrete, micro-porous calcium silicate and the like. The composite precast slab has the advantages that the anti-seismic performance is superior, the composite precast slab is not limited by use territory, the construction is convenient, the composite precast slab is convenient for promoting the industrialization process of the building component production, concrete and steels can be saved, and the self-weight of the structure is reduced.
Description
Technical field
The utility model relates to a kind of building unit, relates to a kind of superimposed sheet composite precast slab particularly.
Background technology
At present, floor structure in the construction work partly adopts the prestressed concrete overlapped slab structure, be about to prefabricated prestressed concrete thin plate and be installed on the strong point of floor structure, the required steel mesh reinforcement of laying on thin plate forms prestressed concrete overlapped slab after pouring into a mould a layer concrete.
With the immediate technology of the utility model be that the inventor studies " a kind of superimposed sheet precast plate " (separate case is applied for a patent).It is characterized in that: comprise prestressing force net form rib, base plate and central layer, described prestressing force net form rib is that the multistage prestressing force rib that concrete rib system forms is, described base plate is the fibre reinforced concrete panel, and described central layer is the lightweight sound absorption heat-barrier material that is compounded on the prestressing force net form rib.
The utility model content
The purpose of this utility model is above-mentioned technology is improved, and a kind of new superimposed sheet composite precast slab is provided, and simplifies building block, reduces concrete consumption, is convenient to suitability for industrialized production.
For achieving the above object, the utility model provides a kind of superimposed sheet composite precast slab, it is characterized in that, comprises prestressing force rib and compound core plate, and described prestressing force rib is a concrete products, and inside is provided with presstressed reinforcing steel, and described compound core plate comprises cross rib and central layer.
Described prestressing force rib is characterized in that, its cross section is shapes such as inverted T-shaped, L shaped, rectangle, and top is provided with rebar connector and suspension ring.
Described compound core plate is characterized in that, the complex of cross rib and central layer, and connected mode is bonding.
Described cross rib is characterized in that, is concrete products, and its cross section is the single of shapes such as rectangle, semicircle or combination shape, and inside is provided with reinforcing bar.
Described central layer is characterized in that, has the shape of combining closely with prestressing force rib and cross rib, and its material can adopt foam concrete, gas concrete and microporous calcium silicate etc.
The utility model compared with prior art, the good effect of its advantage and generation is embodied in:
1, owing to the fibre reinforced concrete base plate is not set, so reduced concrete amount.
2, owing to reduced the parts of forming precast plate, be convenient to make, so help promoting the suitability for industrialized production of building unit.
Description of drawings

The specific embodiment
Below in conjunction with accompanying drawing the utility model is described.
As shown in Figure 1, for the structure schematic top plan view of superimposed sheet in the utility model, comprise prestressing force rib 1, cross rib 2, central layer 3, presstressed reinforcing steel 4, rebar connector 5 and suspension ring 6 with composite precast slab one embodiment.
As shown in Figure 2, for the structure schematic side view of superimposed sheet in the utility model, comprise prestressing force rib 1, cross rib 2, central layer 3, presstressed reinforcing steel 4, rebar connector 5 and suspension ring 6 with precast plate one embodiment.
Ordinary circumstance, enforcement of the present utility model adopt anastrophe to produce, promptly central layer 3 be positioned in cross rib 2 following, implement to comprise the steps:
A. make template, installation in position.
B. shape and size are as required distinguished processing and fabricating cross rib 2 and central layer 3.
C. bond cross rib 2 and central layer 3 form compound core plate, and it is in place fixing in template.
D. lay steel mesh reinforcement, comprise rebar connector 5 and suspension ring 6, tensioned prestressing bar 4, fluid concrete.
E. after the maintenance sclerosis, loosen presstressed reinforcing steel.
Finish the utility model.
Need to prove; the above only is preferred embodiment of the present utility model; rather than to the qualification of technical solutions of the utility model, any the utility model technical characterictic being equal to of being done replaced or corresponding improvement, still within protection domain of the present utility model.According to concrete actual conditions, for example can adopt plain bars to replace presstressed reinforcing steel; Central layer also can be made by other material.
Claims (5)
